What is the alveolar bone proper?

1. A thick layer of bone in the jaw

2. A thin layer of bone lining the socket surrounding the root of a tooth

3. A type of cancellous bone

4. A supportive structure for the tongue

The correct answer is: A thin layer of bone lining the socket surrounding the root of a tooth

The alveolar bone proper is defined as the thin layer of bone that lines the socket surrounding the root of a tooth. This layer is crucial for dental health, as it provides the necessary support and anchorage for teeth in the jaw. It is an integral part of the periodontium, which includes various structures that support and stabilize teeth, highlighting its significance in maintaining the integrity of the dental arch and ensuring the proper alignment and functioning of teeth. In addition to fulfilling this supportive role, the alveolar bone proper houses the periodontal ligament, which connects the tooth to the bone and helps absorb the forces exerted during chewing. This structure is distinct from other types of bone in the body, emphasizing its specialized function in dental anatomy and oral health.
